Blues Brothers 2000 Easter Egg - Who the Heck...?

In the movie "Blues Brothers 2000," when the BluesMobile breaks down just outside of PantherBurn Kentucky (?), Elwood gives everyone a pep talk. At the end of this pep talk he gives a list of names something like this. "...then you will be throwing away the legacies of Elvis Presley, Muddy Waters,... And Robert K. Weiss." (It is a very long list of very famous people) Then one of the band members echoes the thoughts of the audience by saying "Who the Heck is Robert K. Weiss?" He is the producer of the first Blues Brothers Movie.
